Piston Ring Set - 4.470 Bore 1/16 1/16 3/16

The TOTAL SEAL Piston Ring Set CR9190 225 for 4.470 bore represents a premium choice for classic engine builds and racing applications demanding precision-engineered compression sealing. Designed for file-fit installation, this eight-cylinder piston ring kit combines proven ductile iron construction with plasma moly surface treatment to deliver reliable blow-by control and consistent compression across the full engine operating range.

This kit features a 1/16 x 1/16 x 3/16 inch ring thickness configuration with standard tension characteristics optimized for 4.470-inch bore diameter engines. The plasma moly coating on the top and second rings minimizes friction while resisting scuffing under sustained high-load operation—critical for naturally aspirated and supercharged classic race engines. File-fit rings require honing of the bore to exact specifications and careful gap setting, ensuring optimal sealing without excessive side clearance that would compromise compression retention over extended use.

Classic hot rodders, vintage race engine builders, and restoration specialists choose TOTAL SEAL rings for their reputation in delivering measurable ring seal consistency and durability in period-correct and competition powerplants. The standard tension design balances sealing capability with manageable installation effort, making this kit suitable for both first-time rebuilds and experienced engine shops. Proper ring gap setup—verified with a feeler gauge—ensures piston ring longevity and prevents detonation-induced damage during initial break-in and sustained operation.
